Before microscopes, the world of cells and microbes was a mystery, invisible to even the sharpest minds. But once scientists learned to bend light and magnify the unseen, biology was transformed forever. In this article, we’ll explore this journey from simple lenses to the cutting-edge technologies that reshaped science, medicine, and our understanding of the living world. Details >

Confocal and multi-photon microscopy are used for deep tissue imaging, but misconceptions about their utility have led to their misuse. We’ll plunge into tissue depths to reveal a gap in obtaining sharp images that RAYSHAPE – a solution for dynamic aberration correction – fills with clarity and brightness. Details >
How does STED work?
You have heard of STED but don’t have a clear idea how it overcomes the diffraction-limited resolution of confocal microscopes? You maybe even think it to be somewhat complicated? In fact, it isn’t. It’s just physics, smartly applied. Details >
The donut-shaped de-excitation beam is one of the most important practical ingredients for superresolution STED microscopy. But how do you put a hole into a beam of light? Surprisingly, it’s not that difficult if you know how to do it, but it’s very difficult to get it right in practice. Details >
What has to be inside a STED microscope to achieve superresolution? How does its hardware differ from a confocal setup? (Hint: Not very much.) And what does that mean for the user? (Many good things.) Is handling a STED system any more complicated than using a confocal? (Not really.) Important questions – here are some in-depth answers. Details >
Today’s high-end fluorescence microscopy is unthinkable without lasers. Reason enough to take a closer look at these sophisticated light sources. Details >
